Description: The use of reinforcing bars post-installed with an adhesive system is a common design and construction application. Recent revisions to the ICC-ES Acceptance Criteria for Post-Installed Adhesive Anchors in Concrete Elements (AC308) have made it possible for an adhesive system to be approved for post-installing reinforcing bars per the development and splice provisions of the American Concrete Institute Building Code Requirements for Structural Concrete (ACI 318). Therefore, adhesive systems qualified per the provisions of AC308 can now be used with post-installed reinforcing bars designed and installed per the anchoring-to-concrete provisions of ACI 318, and per the development and splice provisions of ACI 318. This presentation will explain the differences between post-installed reinforcing bars designed per ACI 318 anchoring-to-concrete provisions and per ACI 318 development and splice provisions.
